Another person was injured in the shooting, said a police officer on the scene.

The motive of the shooting was not clear.

President Alvaro Colom’s office said in a statement that authorities were investigating whether the shooting of the 74-year-old singer was robbery-related or a targeted attack.

Cabral, who was popular in Latin America, had been in Guatemala on tour.
